The specific embodiment
The spray arm that is used for dishwasher has been shown in Fig. 1 has arranged, said spray arm is arranged and is comprised support arm 10, because it can be installed in the bottom, washing chamber of dishwasher, so that can be around central shaft 12 rotations.For this reason, support arm 10 comprises mounting portion, center 14, and said mounting portion 14 is supported on (see figure 3) in the lining rotationally, and said lining is arranged in the dishwasher regularly.Support arm 12 comprises first support 16 and second support 18.First support 16 has spray arm 20, and said spray arm 20 is rotatably installed around axis 22, and said axis 22 extends in parallel around the axis 12 of its rotation with support arm 10.Spray arm 20 comprises a plurality of nozzles 24, and the jet through nozzle 24 cleaning fluids can be injected on the article to be cleaned that are arranged in the dishwasher chamber.At least one nozzle 24 can be arranged in case spray with vertical direction the water jet of an angle is arranged rotatablely move so that give spray arm 20.Similarly, second support 18 of same support arm 10 can comprise nozzle 26, and said nozzle 26 can be designed as through spraying with vertical direction equally has the driving nozzle of the water jet of an angle as support arm.
Referring to figs. 2 and 3, the theory that bearing block is set that here proposes will be described below.In these figure, Fig. 2 shows traditional spray arm and Fig. 3 shows spray arm manufactured according to the present invention.Especially; Fig. 2 and Fig. 3 show the core of support arm 10; The mounting portion 14 of said support arm 10 is disposed in the tubular liner 28, and in the support arm shown in Fig. 1/attachment arm was arranged, said tubular liner 28 will be the lining that is arranged on regularly in the dishwasher case.Lining 28 comprises central passage 30 in its underpart, in service at dishwasher will be injected into spray arm through said central passage cleaning fluid and arrange.The mounting portion 14 of support arm 10 is cardinal principle parts in a tubular form equally, and said parts are designed to conical part in the embodiment shown in Fig. 2 and Fig. 3.In its lower end, mounting portion 14 has the consistent internal diameter of internal diameter with the central passage 30 of lining 28.In the top, the hollow arm portions 16 and 18 of the central passage 32 connected component braces 10 of mounting portion 14.
Mounting portion 14 comprises first supporting surface and second supporting surface, and support arm leans on lining 28 at said supporting surface.Especially, first supporting surface 34 is provided with the last axle head of hub sections approaching, and the lower end of the second supporting surface setting and mounting portion is approaching.
Comparison diagram 2 and Fig. 3 are visible, and the spray arm that here proposes is arranged in the layout of second supporting surface and designs and is different from traditional spray arm layout.Therefore; Yet it is as shown in Figure 2; In traditional spray arm is arranged first supporting surface 34 and second supporting surface 36 both all be designed to typical annular rim; Said annular rim extends around the tubulose mounting portion, and is as shown in Figure 3, is designed to axially extend to from the mounting portion protrusion the hub sections according to the application's second supporting surface.Though this protrusion can be designed to give prominence to around the annular that the whole circumference of mounting portion is extended basically; Particularly be applied to when arranging when the theory that will propose here such as asymmetric spray arm shown in Figure 1; Wherein asymmtric load is applied on the supporting surface, and second supporting surface is preferably designed so that leading edge, handle or the protuberance (also seeing Fig. 4) of only getting the part extension of circumference around installation portion.
Through second supporting surface is designed with Fig. 3 or mode shown in Figure 4, when effect has asymmetric load on spray arm 10, act on momentum on the supporting surface and compare the momentum that is applied in the legacy system as shown in Figure 2 and reduce.Therefore; Suppose owing to the reason of the distribution of weight on the support arm and also owing to the reason of the reaction force that causes by water jet; The spray arm 20 of said water jet on first support 16 that is installed in support arm 10 sprays; Power F1 acts on first support 16 of support arm 10, and this power attempts to make support arm 10 to tilt with respect to its rotating shaft 12.Therefore, power F2 and F3 are applied between the inwall of first supporting surface and second supporting surface 34,36 and lining 28.Because because power F2 and F3 can produce the friction momentum when arm 10 rotations, it helps reducing these power so that obtain low friction and corresponding little wearing and tearing.
For this reason, according to the present invention, second supporting surface is designed to axially extend to the protrusion the hub sections 28 from mounting portion 14.This design causes the distance between first supporting surface and second supporting surface to increase on the one hand, and causes the radius of second supporting surface to reduce on the other hand.Therefore, during with Fig. 3, should be noted that according to spray arm of the present invention as shown in Figure 3 and arrange at comparison diagram 2, between its first and second supporting surface apart from d2 greater than the respective distances d1 in the conventional apparatus.Simultaneously, arrange that according to spray arm of the present invention as shown in Figure 3 the radius r 2 of its second supporting surface is substantially less than the respective radii r1 in the traditional arrangement.These two sizes cause friction momentum between supporting surface and the bush face with respect to being applied to little in the prior art systems jointly.
Like Fig. 3 and shown in Figure 4; Protrusion 38 can be shaped to the leading edge with streamline section or the shape of handle; For example, be water droplet shape so that reduce dying down of water flow pressure, said current flow through the central passage 32 that lining 28 central passages 30 get into the mounting portion 14 of support arm 10.
As stated; If arrange especially favourable here though the theory that proposes is applied to asymmetric spray arm; It can be applied in the spray arm system that wherein rotatable arm itself is designed to balance equally; Such as the double bracket spray arm of standard or attached spray arm system, wherein the double bracket support arm has spray arm on its each support.Equally; In the spray arm system of this balance; The active force that spray arm unavoidably can bear for the moment or continue, said active force attempt to make the vertical rotating shaft inclination of the mounting portion of turning arm with respect to its expection, owing to the reason of uneven distribution of weight in turning arm; Because it possibly be a uneven water load or caused by the water reaction force of water jet in the support by arm, said water jet is ejected on the article in the washing chamber at dishwasher from spray arm.
Further embodiment according to spray arm of the present invention has been shown among Fig. 5, and this embodiment designs for spray arm especially, and said spray arm can be arranged to the below of below, top, washing chamber or top dishwasher basket.
Especially, Fig. 5 shows a kind of layout, and the spray arm 40 of single support rotatably is installed to intake tunnel 42 in this arrangement, because it can be set between the dishwasher basket of dishwasher basket and below of top.Similarly, arm 40 can be the support arm that is used to support rotatable spray arm.Spray arm 40 comprises the mounting portion, and said mounting portion is designed to short relatively tubular portion 44, and said tubular portion 44 comprises the chimb (46) of the exterior (outer angular) as first supporting surface in the top.Mounting portion 44 is arranged in the ring bush part with annular nib 46, and said ring bush partly is arranged on the bottom of feeding-passage 42.Along the wall of its top, feeding-passage 42 comprises the second ring bush part 50.Mounting portion 44 is provided with the protrusion 52 that the rotating shaft 54 with spray arm 40 extends in parallel.Protrusion 52 have with the embodiment shown in Fig. 4 in protrusion 38 shapes similar, for example, at least in the top, contact bush part 50, it has circular outer shape.Side protrudes 52 towards the feeding-passage that is provided by mounting portion 44 56 within it, and protrusion 52 preferably has streamline section.
Spray arm arrange in service, power F1 acts on the spray arm 40, said power possibly be derived from gravity or water reaction force, frictional force F2 and F3 are applied to first supporting surface and second supporting surface respectively.In view of protrusion 52 less radius r 3, it is minimum that therefore frictional force F3 keeps.
